    Abstract: A remote controlled circuit breaker for battery powered riding toys and method of using is disclosed. The circuit breaker is capable of being installed into standard electrical systems of battery powered riding toys via complementary connectors. If the child encounters danger while riding, the handler of the remote control can push the “Stop” button to switch the circuit breaker, thus preventing electric current flow through the toy. Once danger is averted, the handler of the remote control can push the “Go” button, which switches the circuit breaker to allow current flow from the battery to the motor, and thus allowing movement of the vehicle.

  • Patent number: 3937479
    Abstract: A dolly to facilitate the manual moving and positioning of trailers and other vehicles incorporating ratchet mechanisms to provide a high mechanical advantage for moving the vehicles. The ratchet mechanism can be selected to drive in the forward or reverse direction through a ground engaging wheel. A drive disc is mounted for rotation with the ground engaging wheel and is engaged by pawls from drive and holding ratchet mechanisms. The holding ratchet mechanism is mounted on the frame of the device and the drive ratchet mechanism is mounted on a yoke carrying an actuating handle. The mechanisms also permit coasting in the selected direction only. A brake, mounted on the yoke and controlled by a mechanism on the handle, functions to lock the wheel relative to the yoke. This allows the wheel to be rotated relative to the pawls, releasing locked-in-position pawls. Other selected modes may be used to lock the wheel in position to act as a brake or disengage the wheel completely to allow free movement.
